The Texas Commission on Environmental Quality on Friday approved an investigation report on Tesla\u2019s battery-grade lithium compounds manufacturing facility near Robstown in Nueces County, finding no violation of the plant\u2019s wastewater discharge permit.<\/p>\n

TCEQ began its investigation after workers for Nueces County Drainage District No. 2, which presides over the ditch area, found an unfamiliar pipe stretched across the district\u2019s easement, expelling black liquid into the ditch. The workers filed two complaints with TCEQ on Jan. 20<\/a> and Feb. 9<\/a> about the quality of the wastewater discharged from the Tesla facility.\u00a0<\/p>\n

On February 12, a state investigator evaluated the ditch running alongside U.S. 77, west of Corpus Christi, and the liquid waste from the discharge pipe. The wastewater appeared clear as it flowed downstream, according to state records. Along the banks and in the ditch, there was a heavy growth of algae and vegetation.\u00a0<\/p>\n

The investigator then went to the Tesla facility and met with a senior environmental engineer and manager and collected samples from near the cooling towers and from the pipe leading to the ditch after the wastewater was treated. The lithium refinery plant is permitted to discharge cooling tower blowdown, water treatment wastes and boiler blowdown. Test results for dissolved solids, oil and grease, chlorides, sulfates, temperature and oxygen were all within the bounds of Tesla\u2019s permit, according to the TCEQ investigation.\u00a0<\/p>\n

Steve Ray, a spokesperson for the drainage district, said the district has met with Tesla management three times concerning this situation.\u00a0<\/p>\n

\u201cWe appreciate the cooperation from Tesla, TCEQ and Nueces County and will continue to monitor the discharges as we work to keep drainage ditches in the area operational and safe for our workers and the citizens we serve,\u201d Ray said on Wednesday.\u00a0<\/p>\n

While the electric vehicle company is permitted by TCEQ to dispose of up to 231,000 gallons of treated wastewater per day on average in the ditch, the Nueces County Drainage District wasn\u2019t aware of the permit before its workers found the pipe discharging black liquid into the ditch.\u00a0<\/p>\n

The district workers were performing routine maintenance, clearing overgrown brush and fallen winter branches, when they first reported the black liquid.\u00a0<\/p>\n

\u201cWe told them not to do anything until we saw it,\u201d Ray said. The industrial, dark, wastewater pooling in the county\u2019s ditch came from Tesla\u2019s lithium refinery plant across the way, Ray said, as first reported by KRIS 6 News<\/a>, a local TV station.\u00a0<\/p>\n

The drainage district then set up a meeting with the electric vehicle company about the wastewater, Ray said.\u00a0<\/p>\n

The discharge permit was issued to Tesla in January 2025, according to TCEQ documents. The permit didn\u2019t allow Tesla to use private or public property to transport the wastewater. Under the permit, it was Tesla\u2019s responsibility to acquire whatever property rights were required to use the discharge route, the TCEQ permit<\/a> states.\u00a0<\/p>\n

When asked if Tesla was authorized to construct a pipe to the unnamed ditch, the TCEQ repeated its permit rules. The wastewater compliance report does not include mention of Tesla\u2019s use of the drainage district\u2019s easement. The pipe is still there, Ray said.\u00a0<\/p>\n

TCEQ doesn\u2019t communicate directly with local drainage districts as part of the permitting process, a spokesperson for the agency said.\u00a0<\/p>\n

For individual water quality permits, the TCEQ requires two public notices. Applicants, like Tesla, must publish them in local newspapers. TCEQ also makes notices available online<\/a> for treated wastewater discharge applications received prior to June 1, 2024.\u00a0<\/p>\n

The wastewater permit also requires that there isn\u2019t any significant discharge of floating solids or foam and no discharge of visible oil.<\/p>\n

Tesla did not respond to questions from Inside Climate News about the wastewater disposal nor the use and construction of the pipe.\u00a0<\/p>\n

The electric vehicle company is run by the richest man in the world, Elon Musk, who resides and has multiple facilities in Texas for his various endeavors, including Tesla, SpaceX, X (formerly Twitter) and The Boring Company. Some of his companies have accrued TCEQ violations.\u00a0<\/p>\n

The nearly $1 billion lithium refinery plant in Robstown, Texas, aims to increase the domestic supply of battery-grade lithium hydroxide, a critical chemical compound for making rechargeable batteries, including those for electric vehicles, according to Tesla<\/a>. The site, which started construction in May 2023, processes the lithium without using harsh acids, allowing for the refinery\u2019s byproduct to be a mixture of sand and limestone, the company says.\u00a0<\/p>\n

Ray said that in a discussion between the drainage district and the company, Tesla continued to refer to its wastewater as clear. \u201cIt\u2019s not clear at all,\u201d Ray said. \u201cIt\u2019s black.\u201d\u00a0<\/p>\n

Tesla\u2019s wastewater operations were set as an agenda item for the drainage district\u2019s Jan. 27 public meeting. In a letter<\/a> obtained by KRIS 6 News, a senior manager of the Tesla site said the company could not have a company representative there and wanted to understand any concerns.\u00a0<\/p>\n

Jason Bevan, the senior manager, said in the letter that Tesla is committed to being a good neighbor in the community. The company has partnered with local environmental groups, Bevan wrote, including the Coastal Bend Bays Foundation and The Harte Research Institute at Texas A&M University-Corpus Christi (HRI), the marine research institute working to advance long-term sustainable use and conservation of the Gulf.\u00a0<\/p>\n

The drainage ditch flows to Petronila Creek and ultimately to Baffin Bay. The saltwater bay is often called the \u201cjewel\u201d of the Texas coast and has supported longtime fishing in the area. But over four decades, the ecosystem\u2019s health has deteriorated, according to HRI publications<\/a>.<\/p>\n

The Baffin Bay watershed in South Texas is increasingly vulnerable to flooding caused by intense rain and corresponding stormwater runoff, which carries pollutants that degrade water quality and threaten wildlife populations, stated the research institute.\u00a0<\/p>\n

Ensuring the quality of the area\u2019s waterways and environment is a priority to the drainage district, Ray said. While the district looks to undergo its own water quality testing of the ditch, Ray is concerned about the sensitivity of the bay\u2019s ecosystem. \u201cI do want to have a clean environment for my children and grandchildren and great grandkids,\u201d Ray said.\u00a0<\/p>\n

As Tesla is one of the first industrial clients the drainage district is dealing with in its rural area, there aren\u2019t other examples of how large corporate clients transport its wastewater and notify the district, Ray said. But not seeking out permission to use its easement and build a pipe is not the precedent they\u2019re looking to set. \u201cThey went across our easement without letting us know,\u201d Ray said. \u201cWe need to be informed about it and we weren\u2019t.\u201d\u00a0<\/p>\n

Revelation of the pipe has put the district in an uncomfortable position. \u201cIt\u2019s not that we are anti-industry; we\u2019re very pro-industry,\u201d Ray said. \u201cThis is not really directed at Tesla itself, this is directed simply at ensuring that our workers and the citizens that we serve have a clean environment.\u201d\u00a0<\/p>\n
